IRIN: Dhaka residents threatened by heavily polluted rivers

Several voices warn that the heavy pollution of the rivers around Dhaka has affected the aquatic life beyond rescuing, IRIN reports. Also, this impacts the lives of the Bangladeshi, who need to change jobs, live with the stench and risk skin diseases and other health hazards. Earlier this year, the industral sector admitted that is lacks social responsibility plans, especially when it comes to effluent treatment plants.

"The concentration of organic pollutant in the Buriganga is 17 times higher than the allowable limit of 3mg per litre. Chemical pollutants like ammonia, aluminium, cadmium, lead and mercury have also been detected in the Buriganga," SM Mahbubur Rahman, head of the water resource planning division of the Institute of Water Modelling (IWM), said.
The lone sewage treatment facility operated and maintained by Dhaka Water Supply and Sanitation Authority (DWASA) has a treatment capacity of 0.12 million cubic metres per day, while the daily volume of sewage generated in Dhaka city is 1.3 million cubic metres.

Furthermore, the islands in Bangladesh are severely affected by rising tydes and cyclones - especially since tropical cyclone Aila destroyed much of its dykes and flood barriers earlier this year inMay. The Guardian posted an album with pictures of the repair efforts.
